190 BOTANY. as great as the width. E. Australis from Austraha, as weU as Cicendia from Europe, have stigmas like the American species, but E. Chilensis (at least a specimen collected by Ochsenius in Valdivia, which I refer to that species) differs from all the others in having elongated, cuneate, emarginate stigmas. The seeds of Erythrcea are identical with those of a large group of Gentianece, which comprise perhaps aU of Grisebach's Chironiece and Chlo- rece, being very numerous and very small, from | to scarcely more than J"° in the longer diameter, and, when fully mature, globose or oval, with their surface favose-reticulate. The North American genera belonging to this group may be arranged thus : 1. Stamens inserted in the tube: Eeythe^a. Eustoma. 2. Stamens inserted in the throat: Sabbatia. Miceocala. Chloea, Chieonia, and SEBiEA of the Old World also belong here. My investigations have convinced me that the genus Cicendia, or at least its typical and original species, C. pusilla, is nothing but a reduced form of Erythrcea, distinguished from it only by its small oval anthers, less than 0.5"" in length, too short to twist much, but still, when drying, some¬ times twisting a little. Its stigma is by no means capitate, but regularly bi-lamellate, and, much like that of the American species, triangular-flabel- late, and broader than long. The fiowers are 4-parted, which often occurs in genuine species of Erythrcea; seeds 0.4"" long, large for the size of the plant. It will have to bear the name Erythrcea pusilla. Eeythe^a Douglasii, Gray, Fl. Calif 1, 480; Syn. 113.—Slender, a span to a foot high, loosely and paniculately branched, usually sparse- flowered ; leaves from oblong to linear, acutish; flowers on strict, slender pedicels, 4-5" wide; lobes of the pale pink corolla obtuse, much shorter than the tube; anthers usually only 1"" long, style short, stigma about 1"" wide; seeds sub-globose, 0.4"" in diameter.—Arizona, Utah, and northwestward to Oregon. This plant has been confounded by Mr. Watson with his E. Nuttallii, which, however, is a smaller and more leafy plant, with larger flowers and much larger seeds (0.65"" long), but much smaller stigmas.
